Logging Amazon ECS API Calls with AWS CloudTrail

Amazon ECS is integrated with AWS CloudTrail, a service that provides a record of
actions taken by a
user, role, or an AWS service in Amazon ECS. CloudTrail captures all API calls for
Amazon ECS as events,
including calls from the Amazon ECS console and from code calls to the Amazon ECS
API operations.

If you create a trail, you can enable continuous delivery of CloudTrail events to
an Amazon S3 bucket,
including events for Amazon ECS. If you don't configure a trail, you can still view
the most recent
events in the CloudTrail console in Event history. Using the information
collected by CloudTrail, you can determine the request that was made to Amazon ECS,
the IP address from
which the request was made, who made the request, when it was made, and additional
details.

Amazon ECS Information in CloudTrail

CloudTrail is enabled on your AWS account when you create the account. When activity
occurs in
Amazon ECS, that activity is recorded in a CloudTrail event along with other AWS service
events in
Event history. You can view, search, and download recent events in your
AWS account. For more information, see Viewing Events with CloudTrail Event History.

For an ongoing record of events in your AWS account, including events for Amazon ECS,
create
a trail. A trail enables CloudTrail to deliver log files to an Amazon S3 bucket. By
default, when you
create a trail in the console, the trail applies to all regions. The trail logs events
from
all Regions in the AWS partition and delivers the log files to the Amazon S3 bucket
that you
specify. Additionally, you can configure other AWS services to further analyze and
act upon
the event data collected in CloudTrail logs. For more information, see:

All Amazon ECS actions are logged by CloudTrail and are documented in the Amazon Elastic Container Service API Reference. For
example, calls to the CreateService, RunTask and
DeleteCluster sections generate entries in the CloudTrail log files.

Every event or log entry contains information about who generated the request. The
identity information helps you determine the following:

Whether the request was made with root or IAM user credentials.

Whether the request was made with temporary security credentials for a role or
federated user.

Understanding Amazon ECS Log File
Entries

A trail is a configuration that enables delivery of events as log files to an Amazon
S3 bucket
that you specify. CloudTrail log files contain one or more log entries. An event represents
a single
request from any source and includes information about the requested action, the date
and time
of the action, request parameters, and so on. CloudTrail log files are not an ordered
stack trace of
the public API calls, so they do not appear in any specific order.

Note

These examples have been formatted for improved readability. In a CloudTrail log file,
all
entries and events are concatenated into a single line. In addition, this example
has been
limited to a single Amazon ECS entry. In a real CloudTrail log file, you see entries
and events from
multiple AWS services.

The following example shows a CloudTrail log entry that demonstrates the
CreateCluster action:
